8314 "T" field selectors create DLT relative fixups for accessing
8315 globals and statics in PIC code; each DLT relative fixup creates
8316 an entry in the DLT table. The entries contain the address of
8317 the final target (eg accessing "foo" would create a DLT entry
8318 with the address of "foo").
8319
8320 Unfortunately, the HP linker doesn't take into account any addend
8321 when generating the DLT; so accessing $LIT$+8 puts the address of
8322 $LIT$ into the DLT rather than the address of $LIT$+8.
8323

8394 If a symbol is reduced to a section symbol, the assembler will
8395 adjust the addend unless the symbol happens to reside right at
8396 the start of the section. Additionally, the linker has no choice
8397 but to manipulate the addends when coalescing input sections for
8398 "ld -r". Since an LR% field selector is defined to round the
8399 addend, we can't change the addend without risking that a LR% and
8400 it's corresponding (possible multiple) RR% field will no longer
8401 sum to the right value.
8402
8403 eg. Suppose we have
8404 . ldil LR%foo+0,%r21
8405 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8406 . ldw RR%foo+4(%r21),%r25
8407
8408 If foo is at address 4092 (decimal) in section `sect', then after
8409 reducing to the section symbol we get
8410 . LR%sect+4092 == (L%sect)+0
8411 . RR%sect+4092 == (R%sect)+4092
8412 . RR%sect+4096 == (R%sect)-4096
8413 and the last address loses because rounding the addend to 8k
0234cb7c 8414 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8415
8416 In cases where the LR% expression is identical to the RR% one we
8417 will never have a problem, but is so happens that gcc rounds
8418 addends involved in LR% field selectors to work around a HP
8419 linker bug. ie. We often have addresses like the last case
1cd1c99b
